These data are intended to represent baseline data for wildlife communities and habitat conditions in these parks. They can be used to assess and monitor the park's ecological viability and sustainability.
These data are the summary statistics calculated for trees and snags from the three 0.05-ha circular plot habitat samples taken in 2005 each at the 15 sample points at Spears and Didion Ranches, Placer County, California. There were three 0.05-ha circular habitat sampling plots at each of the 15 sample points. To be counted, trees had to be > 4" dbh and within the 12.6 m radius plot, while snags had to be > 4" dbh and > 9.8 ft tall and within the plot.
